RectorSeal Introduces Flaretite, the HVAC/R Tubing Flare Leak Preventative

New ISO and NFPA standards strongly recommend seals for all fittings.

Flared connections fitted with Flaretite Seals are today’s answer to low cost, high integrity, “Zero-Leak” fittings, while complying with new international standards. This unique seal may be fitted to SAE, refrigeration and gas fittings. The introduction of the Flaretite Seal eliminates the weakness in the original flare design.

Evolving higher pressure and more demanding hydraulic systems expose the metal to metal flare fitting which makes it very difficult to obtain a permanent leak free flared fitting joint. Leaks are most commonly caused by misalignment, surface damage and vibration in the field. When inserted into a fitting, the concentric rings form multiple seals down the face of the flare, while the Loctite coating fills minor imperfections, dramatically increasing the integrity of the fitting.

The result is the Flaretite Seal is a permanent, “Leak-Free”connection, which exceeds the performance of today’s ORFS fittings, and at significantly lower cost. Our seal maintains the low profile, versatility, and world-wide availability of flared fittings.
